Oh, the excitment when the teacher wheeled out the massive television so you could watch a schools' TV programme!
Having to queue for the cinema - the queue for ET was epic, and an event in itself.
Properly knowing your bank manager. I used to take mine a bottle of sherry every Christmas when I was a student/first started work. We'd have a little chat and he'd tell me off for sending letters asking for things like an overdraft for 'sex drugs and rock and roll'. He also had a framed photo of one of my cuddly toys that I had sent him, telling him I had a wine habit and a stuffed monkey to support. When I took him a retirement gift in my late 20s, he said he could retire happy, knowing my finances were in order.
No McDonalds, only Wimpy, and milkbars. There was still a milkbar in Welshpool until the 1990s IIRC, really strange places!
Renting televisions. And dads being able to repair televisions.
Dad spending every Saturday morning under the car with his Haynes manual.
Spending hours playing 'Pong'. We thought we were so high tech!
Getting internet in 1995 and spending about 2 excited hours waiting to fully download a picture of Socks the Whitehouse cat.
Sitting with a washing up sponge and sticking green shield stamps into books, then going to the petrol station to get a set of glasses or whatever. I wonder if anyone did ever save up enough to get a car?
And on Halloween we would have hollowed out turnips, not pumpkins. Trick or treat was much less of a thing than 'penny for the Guy'. What didn't seem weird then, but does in retrospect was that the best bonfire and fireworks was hosted by the local convent.
